BME 121Quantitative Physiology: Organ Transport SystemsFinal ExamWinter 2016March 18thName: _______________________________ID #:_______________________________I attest that I am registered for this course and am the person listed above.Signature: ____________________________1
1. True or False with short answer justification (20 points, 4 points each)Read each question carefully, answer true or false (1 point), AND justify answer in 1-2sentences (3 points)A.The pressure generated by the right ventricle is significantly lower than that of the leftventricle, and thus the volumetric flow rate through the pulmonary circulation is lessthan through the systemic circulation.B.Blood is a Casson fluid, which means that it can display both Newtonian and non-Newtonian behavior.C.The bundle branches and Perkinje fibers slow down, distribute, and redirect theelectrical impulse passing through the heart, which is critical for proper ventricular fillingand ejection.D.Osmotic pressure is a driving force for water transport that is directly proportional todifferences in solute concentration, and the amount of water transport will always besufficient to equilibrate the concentrations.E.Baroreceptors are specialized tissues in the arterial circulation that sense bloodpressure through tissue stretching. Increased stretching will likely result in decreasedcardiac output and/or peripheral resistance.Name: _______________________________________2
